To all whom t may concern: y Be it known that BENJAMIN 'll`. HEADLEY, Panne H. THOMPSON, deceased (whose executrix is ltnNA M. THOMPSON), and Devin e RvIN DU Bols, all citizens of the "United States, and residing at Millville, 1n the county of Cumberland and State of New Jersey, have invented a new and useful lmprovement in Transfer Mechanisms for i0 Vial-Working Machines,'of which fthe following is a full, clear, and exact descrlption. The present invention relates broadly to a transfer mechanism, and 'more particularly to a mechanism of this type adapted to w transfer vial blanks from a vial necking machine to a vial bottoming machine, a1-

though its use in this respect is not limited.

Anr important object of the present in-` vention is to provide a transfer mechanism 2c ada ted to be operated in timed relation to a p urality of lcarriers for automatically transferring blanks from one carrier to theother.

Another object of the present invention is to provide a transfer mechanism of the character described adapted to raise blanks from suitable support on one carrier, transfer the same to supports on another carrier, and then lower the same-into engagement there.-

i so with.

' Still anotherobject of the present invention is tdprovide a feed device for vial working machines adapted to feed vial blanks thereto in timed relation to the opera5 ation of the machine.,

The foregoing and other objects, together with their attendant advantages, will be apparent as the invention becomes better understood by reference to the accompanying 4c specilication and drawings forming a part hereof, it being premised that changes may be made in the various details and the manner of o eration within the scope of the appende claims without departing from the spirit of the invention.

F i ure 5 is a view similar to Figure 4 but in w ich the supporting member has been moved away from the blank and the blank deposited on the blank support on the endless carrier of the bottoming machine;

Figure 6 is a detail sectional view, on an enlarged scale, on the line VI-Vl of lFigure l; and

Figure 7 is a diagrammatic plan view of the respective carriers.

ln the art of vial making, itis customary to first prepare Itubular blanks havin substantiallv twice the length of a finished These blanks are then necked byl a suitable necking machine, and thereafter fed to a bottoming machine, by which the blanks are separated and bottomed, or fed directly to the bottoming machine without necking to form wide mouthed vials. In either case, it is desirable to provide means for delivering the blanks to the bottoming machine in timed relation to the operation thereof, and it is the pur ose of the present invention to effect such elivery.

Referring more particularly to the drawings, there is illustrateda preferred embodiment of our invention for transferring vial blanks from the station A to the station B. As shown in the drawings, the blanks are successively brought to the station by an endless carrier, l, operating over a sprocket 2, carried by a shaft 3, journaled `in the frame 4 of a necking machine of any desired construction constituting no part of the present invention. Allt will be apparent that the endless carrier may be of any desired construction capable of bringing the blanks' to the station A, and may lbe .provided with supports 5 for this purpose.

Adjacent the delivery' end of the carrier 1 is mounted a bottoming machine supported on a suitable frame 6, and comprislng an endless carrier 7, operating over a sprocket 8 and provided with a series of blank supports 9. The s rocket may be carried by a shaft l0, suitably 'ournaled in the frame 6 and driven in any esired manner. IThe car- 4end thereof a V-block 25.

riers 1 and 7 each preferably comprises two spaced flexible chains operating 1 in pairs, with each pair in the same horizontal plane and adapted to support a vial blank V, be-

tween the respective supports thereon, as

The lever 15 is carried by a pin 17 mounted in suitable bearings in the frame 6 of .the bottoming machine. Extending parallel to the shaft 10 is a second shaft 18 adapted to\ be driven in any desired manner and provided with a cam 19 having a groove 20 therein for the reception of a roller 21 on the lever 15. This mechanism is arranged to shift the lever 11 from the position shown in Figure 3 to the position shown in Figure 4, as will be more clearly described hereinafter.

Pivotally mounted on the pin 12 at one side of the lever 11 is a second lever 22 located between stop pins 23 on the lever 11. Slidably mounted in one end of the lever 22 is a stem 24 having connected to the upper The stem 24 is held in position in the slotted. end of the lever 22 by means of plates 26, which are connected to the lever 22. Extending through a slot 27 in one of the plates 26 is a roller 28. This roller also extends into a cam slot 29 in the lever 11.

The lower end of the lever 22 is provided with a segmental friction block 30, which is engaged on each side by leather faced friction strips 31 supported by the. bracket 13. As clearly shown in Figure 2, this bracket is forked, and each fork is provided with a plurality of hollow bosses 32 and openings 33. Threaded into each of the strips 31 are three tap screws 34 extending through the openings 33, while short pins 35 connected to the strips 31 extend into the hollow bosses 32. Springs 36 are provided within the recesses in the bosses 32, and at one end engage the strips 31, while at the other end they engage followers 37 adjustable by means of set screws 38 mounted in screw plugs 39 in the ends of the bosses 32. By adjusting the screws 38, the friction between the strips 31 and the friction block 30 on the lever 22 can readily be varied.

Assuming the parts to be in the position illustrated 1n Figure 3, with the V-block 25 in engagement with one of the blanks V at the station A, the rotation of the cam 19 in the direction of the arrow will act through the roller 21 to depress the lever 15. This will move the entire transfer mechanism illustrated in Figure 1 about the pin 12 and Maase@ bring the same to the position shown in Figure 4i, with the vial blank V above one of the blank supports 9 at the station B. The roller 21 on the lever 15 is now at the high point of the groove 20l in the cam 19, and immediately thereafter will be` raised by continued rotation of the cam to move the lever` 11 relative to the lever 22, and thus cause the roller 28 to ride downwardly in the cam slot 29 in the lever 11 and thereby lower the stem 24 and V-block 25 out of engagement with the vial blank into the position. illustrated in Figure 5. 1t will be apparent that this relatlve movement between the levers 11 and 22 is accomplished due to the friction between the block 30 and the strips 31, which tends to hold the lever 22 against movement until the travel'of the roller 28 in the cam slot 29 is completed. Continued operation of the cam 19 will raise the lever l5 and swing the transfer mechanism about the pin 12 to the position illustrated in Figure 3, but with the V-block 25 in its lowered position out of engagement with the vial blank at the station A. Thereafter, the V-block will be raised into engagement with the vial blank due to the relative Inovement between the levers 11 and 22, which causes the roller 28 to ride. upwardly in the cam slot 29 into the position illustrated in Figure 3. A. further movement of the parts will repeat the operation described, thereby edecting a periodic transfer of vial blanks to the bottoming machine in timed relation to the operation thereof.-

lWhile the various detalls of thenecking machine and the bottoming machine referred to herein, and the driving means for operating the same in timed relation, constitute no essential feature of the present invention, the construction may be in accordance with the disclosure'of our eopending application Serial No. 338,179, filed November 15, 1919, of which this case is a division.

' rli'he advantages of the. present invention .arise from the provision of means operating in timed relation to the operation of the vial working machine for successively delivering vial blanks thereto as required. y

Further advantages of the present invention arise from the use of a .transfer mechanism adapted to raise vial blanks from supports on one carrier and gently lower the same into engagement with supports .on another carrier. i
